Specification of Letters Patent.

Patented NOV. 27, 1906.

Application fila l September 1, I905. Serial No. 276.700.

To all whom it may concern:

Be it known that I, WILLIAM FEHR, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inHeddle- Frames for Looms, of which the following is a specification.

My invention has relation to a heddleframe for looms, and in suchconnection it re lates to such a construction and arrangement of theparts that a strong, light, and substantial frame may be readilymanufactured.

The principal object of my'present invention is to provide in aheddle-frame in connection with the relatively broad top and bottomcross-bars of the frame and the crossrods upon which the heddles aresupported of the end straps or braces each formed of two members, eachmember consisting of a thin flat strip of metal bent at either end intoa half-loo to surround or inclose a cross-bar and eac member being bentintermediate of its ends to form half of a sleeve into which thecross-rods may be passed when the two members are secured together.

The nature and scope of my invention Wlll,

be more fully understood from the following description, taken inconnection with the accompanying drawings, forming part hereof, in whichFigure 1 is a broken front elevational view of a heddle-frame embodyingmain features of my invention. Fig. 2 is a front elevational view ofpart of a frame, but illustrating a slightly-modified construction. Fig.3 is an enlarged front view of one end of one of the straps connectingthe top and bottom frame-pieces together. Fig. 4 is a side view of Fig.3. Fig. 5 is an enlarged front view of one end of the otherconnecting-strap. Fig. 6 is a side view of Fig. 5. Fig. 7 is an enlargedvertical sectional view of the frame; and Fig. 8 is a view similar toFig. 7, but illustrating a modified form of connecting strap.

Referring to the drawings, a is the top and b the bottom bar of theframe. These bars a b are relatively broad and formed of wood or metal,as desired. The top and bottom bars a and Z) are held in parallelrelationship by the end straps d, each of which is formed,-

preferably, of two members, and each member is made of thin flat metal.Each member of a strap (1 is bent at either end, as at d", 5 5 to form ahalf-loop, and is also bent, as at d adjacent to each end into ahalf-sleeve-like projection. When the two members are assembled andsecured together, there is formed at each end a loop surrounding the topor bottom bar a or b of the frame anda sleeve into whichthe cross-rod fmaypass. The cross-rods f support the heddles g in the usual way and arein turn partly supported by the bars a and b in any suitable way. 0 5One way of thus supporting the cross-rods is illustrated in Fig. 1 andconsists in securing the cross-rodfby a hookf to a barf which in turn issecured by the hook-pins f to the top a or bottom I) of the frame. Asecond way is illustrated in Fig. 2 and consists in hooking thecross-rod f directly to the bar a or (I; by a hook-pin f which entersthe bar a The members of each strap (1 are united to 7 5 each otherpreferably by means of rivets 1 and, if desired, these rivets d may notonly pass through the members of a strap (1, but also through a bar a orb of the frame, as clearly illustrated in Fig. 7. The cross-rods f havemore or less play in the sleeves formed in the straps d. In order thatthe cross-rods f may be locked against longitudinal movement and may becapable of longitudinal adjustment in the frame, I provide the followingmeans: Each member of strap d is bent, as at (1 so that when assembledeach strap has an eye or opening (1 some distance from the sleeve d Intothis eye (1* one end of a wire hook h is swiveled, and the other end of0 said hook is arranged to enter and fit in an opening it in the end ofa cross-rod f, as clearly shown in Figs. 1, 2, 3, and 4. The end of thehook h is turned at right an les to the rod f and then bent parallel tothe face of said rod f to prevent the accidental dislodgment of the hookfrom the rod To advance or retract the cross-rod f in the straps d, theend of said rodf which is not locked by the hook It has a screw-threadedstem f projecting through a loop (1 and arranged to receive two nuts f fone of which may be turned to advance or retract the cross-rod f in thestraps and the other may be turned to lock or release the first nut.

In Fig. 8 a modified form of strap is illustrated in which the twomembers of the strap the top and bottom bars with an end strap 3 5 arereinforced by stiffening-pieces d inserted between the members andlocked thereto by the rivets or other fastening means.

The construction of frame is simple, light, and very strong. The endstraps serve to hold the top and bottom bars of the frame in accurateparallel relationship and also serve as a firm and unyieldingbearing forthe crossbars f, which support the heddles.

Having thus described the nature and object of my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. In a heddle-frame, the combination of the top and bottom bars withthe end straps each consisting of a plurality of thin fiat metallicstrips each bent at either end into a half-loop and said strips adaptedwhen fastened together to surround the top and bottom bars of the frameand to hold said bars in parallel relationship to each other.

2. In a heddle-frame the combination of the top and bottom bars of theframe with metallic end straps uniting said bars in parallelrelationship, each strap consisting of thin strips of metal bent at eachend into a half-loop to partly surround the top or bottom bars of theframe, and fastening means passing through the members of the straps andthrough said bars of the frame to thereby secure said strap members toeach other and to said bars of the frame.

3. In a heddle-frame, the combination of consisting of metal strips,said strips being bent at each end and united to form at each of saidends a loop for the reception of the top and bottom bars of the frame,and rivets uniting said strips firmly to each other.

4. In a heddle-frame, the top and bottom bars, the end straps eachconsisting of metal strips, said strips being bent at each end andunited to form at each end a loop for the reception of said top andbottom bars, and each outer strip being bent adjacent to either end sothat when united sleeves are formed, in combination with a cross-barsupporting the heddles and adapted to enter the sleeves formed in saidstraps,v and to be secured therein, and means for fastening the stripsto each other, substantially as described.

5. In a heddle-frame, the combination of the top and bottom bars with anend strap consisting of metal strips, each strip bent at each end andunited to form at each of said ends a loop for the reception of the topand bottom bars of the frame, stiffening-pieces inserted between thestrips and fastening means adapted to unite the strips andstiffening-pieces firmly together.

In testimony whereof I have hereunto set my hand this 29th day ofAugust, 1905.

WILLIAM FEHR.
